They are still in business. They have made all kinds of lifting equipment for many years. I
was just looking at screw jacks on E Bay and many that are called "House,Barn,Railroad" jacks are theirs. They all seem to be real antiques but still functional. Some had 10" of travel. Sort of a prehistoric Esco jack. They look like they would be very good for replacing a motor mount on my pick up, that is already on jack stands. I don't like using a hydraulic jack for safety reasons and fine height adjustment is difficult, especially when lying in your back. They make tall ones for vehicles on a lift at a reasonable price but nothing similar for a car on stands. This brand was new to me too, until I started looking for screw jacks
